. BLOW-LAMP.

SPECIFICATION forming part of Letters Patent No. 251,993, dated January Application filed September 16, 18H1. (No model.)

To alt whom it may concern` y Beit known that I, RICHARD THOMAS BISH- OP, of St. Louis, Missouri, have invented certain new and useful Improvements in Blow- Lamps; and Ido hereby declare that the following is a full, clear, and exact description ofthe invention, which will enable others skilledin the art to which it appertains to make and use the same, reference being had tothe accompanying drawings, which form a part of this specilication. y y

Figure l is a perspective view, partly in sec-l tion, of my improved blow lamp or paintbreamer. Figs. 2 and 3 are similar views, illustrating modifications of my invention; and Fig. tis a section on the line .fc 0:,"Fig- 3.

Corresponding parts in the several figures are denoted by like letters of reference.

This invention relates to blow-lamps or paintbreamers for throwing a strong jet of ame and heat upon any particular spot or point where it may be needed-a kind of apparatus frequently required by plumbers, gas-iitters, painters, carriage-manufacturers, and others; and my invention consists in the improved construction and arrangement of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

ln Fig. l of the drawings hereto annexed I have illustrated the simplest form of my invention, which consists `of a box or casing, A, in the bottom of which is arranged a small stove or lamp, B, filled with some suitable absorbent-such as asbestus or spon ge-and hav? ing a central air-supply pipe.

Adjoiningthe rear side of the casing A is f1tted a vessel or reservoir, D, provided` withV a screw-plug, E, by removing which the vessel may be `filled with alcohol, hydrocarbon, or any burning-duid which is to be employed. The plug E is provided with a centrally-located safetyvalve,F, heldin place by acoiled spring, G, asshown. r

H is a tube or pipe, of copper, brass, or other suitable material, passing from the bottom of reservoir D through the back ot casing A, within which it is coiled above the lamp B, its upper end passing back into the reservoir D.

I is a pipe arranged verticallyin said reser 3, Issa.

Voir, and provided at its upperend with a 5o screworregulating-cock,J,thehandleofwhich extends above the reservoir, as shown; Just below the top of the reservoir the pipe I has openings K for the passage of steam or The lower end of pipeI passes through the bottom of` the tank or reservoir, through the back of the casing, and upward within the coiled pipe-H, between the coils of which it is provided with one or more openings, L, facing the front of the casing,`which has an opening, 6o M, for the blast. N is a suitably-arranged handle, by which the device may be conveniently held by the operator. y

When the lamp and reservoir have been filled the lamp is lighted, thus heatingthe coil and 65 the fluid contained therein and generating gas, which escapes into the top of tank D, from whence it passes through cock J into pipe I, and out through the perforations or burners K of the latter, on escaping from which it is 7o immediately ignited by the naine of the stove or lamp, thus producing a strong and exceedingly hot blast, which may, however, be easily regulated or extinguished by manipulatingthe 000k J. 7 5

By the handle N the device may be readily manipulated so as to apply the blast where desired.

By the construction shown in Fig. 2 of the drawings the casingA, lamp B, reservoir D, 8o with its screw-plug and safety-valve, and the pipe I, with its con nections, are constructed and arranged substantially as above described; but to the pipe H (which is in other respects arranged as above specilied) is attached, ata point between the tank and the casing, a small plunger-pump, consisting of acylinder, O, having a ball-valve, l?, arranged above a three way cock, Q, and connected by a pipe, It, with the pump-body S, which also serves as a han- 9o dle to the device, and which contains a ballvalve, T, and a piston or plunger, U, the stem of which is forced in an upward direction bya coiled spring, V, arranged between the top button of said stem and the stuing-box W, in which it works, so that it may be readily manipulated by the operator holding the device. From the cylinder O a supply-pipe, X, leads to the stove or lamp B, which may thus, when the three-way cock Q is properly adjusted, be

filled by working the feed-pump. By turning the cock the pipe X may be closed andthe supply directed into the coiled pipe H, or both may be closed, as will be the case when the lamp B and reservoir D are both lled. The feed-pump draws its` supply from a suitablylocated supply-tank, Y, with which it is to be connected by a flexible tube, Z, having a stopcock, A.

The construction,as shown in Fig. 2,is preferable when a continuous blast is to be maintained t'or a long time, it being simply a convenient mode ot' filling the tank D and the lamp, thus enabling the machine to be made small, lightand easily manipulated.-

The device shown in Fig. 3 differs from that in Fig. 2 mainly in the construction of the casing A, which has an arched open front, andin which the coiled pipe H is arranged in acurved position, as shown. The burner-pipe I, instead of being rigid, as above, consists of a jointed cr swiveled section, B', enabling the llame or blast to be thrown successively in several directions. This deviceis speciallyadaptcd for the use of carriage-builders, but is of course not necessarily conned to such use.

From the foregoingdescription, taken in connection with the drawings hereto annexed, the operation and advantages of myinvention will be readily understood. It is simple, inexpen- .Q i' l 251,993

sive, easily manipulated, and far more etfective than devices now in use.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- 1. The combination of the casing A, lamp B, reservoir D, coiled pipe H, and burner-pipe 1, all arranged and operating substantially as herein described, for the purpose set forth.

2. Thecombination ofthe reservoir, the lamp B, the heating-coil, andthe burner-pipe I, having gage-cock J and. perforations K, substantially as described, for the purpose set forth.

3. The combination cf the casing, lamp, coiled pipe H, and the plunger-pump O S, the body ot' which, S, forms a handle to the device, the cylinder O, having a three-way cock, Q, and feed-pipe X, and a suitable tank, Y, and

flexible tube Z, all arranged and operating.

substantially as described,for the purpose set forth.

4. In a blow -lamp or paint-breamer constructed substantially as described,- the jointed cr swiveled burner-pipe, as and for the purpose shown and specified. p

In testimony that I claim the foregoing .as my own I have hereto affixed my signature in presence of two Witnesses.
